Subject: [PATCH] Comments on style

* If we do not code CR and/or LF into the <p> tag, then is works fine more universally (e.g. on my Braille terminal).
* -vf is an alias for -filter:v. If we use it here, then we should at least mention this alias also in the other recipes.
* Here we use the alias -acodec, otherwise the abbreviation -c:a of -codec:a. This could be confusing for newcomers. At least a remark is needed.
